The folks at DailyTech have gotten their hands on some new details about AMD's upcoming next-generation processor lineup. Rumors about those chips already appeared last year, but judging by the new information, AMD might have changed its plans slightly since then. The site says the desktop version of the Barcelona core, AMD's quad-core flagship, will be dubbed "Agena" and will run between 2.4GHz and 2.6GHz. Agena will have 512KB of L2 cache per core and 2MB of shared L3 cache per chip, and it will bear a thermal design rating of 125W.

On the mainstream front, AMD's next-gen dual-core processor will be called Kuma. Like Agena, it will have 512KB of L2 cache per core and 2MB of shared L3 cache per chip, but it will be clocked between 2GHz and 2.9GHz. TDP will be 65W or 89W depending on the model, although AMD reportedly plans to release 35W Energy Efficient models. On the low end, a "Rana" chip will succeed current Sempron processors. Rana will be a version of Kuma with no L3 cache and clock speeds ranging from 2.1GHz to 2.3GHz. DailyTech says Agena and Kuma will launch in the third quarter, with Rana and energy-efficient Kuma variants to follow in the fourth quarter.

Too bad they are far, far away from hitting the market. Intel will rule for a long time...

Kuma looks like the dual-core K8L core processor to get, if you're buying AMD. Far more L3 cache per core :)

Seems that AMD can do ~30W/core up to 2.6GHz on their current 65nm node (+5W for memory controller + HT), hence 125W quad-core and 65W dual-core.

Now if a K8L core is on average 20% faster than a K8 core, that makes a 2.6GHz core equivalent to a 3.1GHz K8. I don't see 65W dual-core 3.1GHz K8s on the market yet...

Of course, it will probably be 10% faster for integer tasks, and 30% faster for floating point - pessimistically. It could be 20%/50% I guess, we'll wait for the reviews for that!

So:

Q2: Server K8L Barcelona Quad Core
Q3: Desktop K8L Agena, Kuma
Q4: SFF Kuma, Desktop Rana

And Intel's Q4? Penryn has two-threads per core ... hmmm. AMD needs to up the clocks IMO, even with the improved IPC.
